"Airtemp sensor on unsupported car?

Some PowerFC's have support for the AirTemp sensor under MONITOR but the car itself does not utilize a factory air temp inlet sensor. I attempted to hook up an airtemp sensor on my ECR33 PowerFC and fried the powerfc and damaged a sensor on my car. The concept was to look at which pin on the BNR33 PowerFC the air temp sensor was connected on and then try and replicate this on the ECR33 PowerFC. I tried this and it did not work, I tried an adjacent wire and it fried the PowerFC. It has since been fixed and all is working but I do not recommend you try to get this working. It may work out costly like it could have been in my case. "

Thats for the R33.. We are discussing the R32 PFC.

SK really needs to clarify again.

Yes this mod works fine for BNR32 + HR32 PowerFC. Only ECR33 PowerFC it goes bang

[Craved]

oh. whoops ..

damn sucks for us

thiwas the only mention of it that i had seen.

nice FAQ though Paul !

[paulr33]

ah i see your on ecr33 powerfc, hehe yeah it doesnt work

feel free to try though

[Craved]

umm i think i'll learn from your examples thanks

[paulr33]

haha yeah good idea

shoulda seen the look on my face when i had pacman characters running around on the hand controller screen and pshyco ticking noises coming from the powerfc

im sure that would have been followed by some VERY colourful words :lol:

hey guys. im new to sau, but i jst thort id thro my 2c worth in... im currently building a rb25/30 setup, using a complete factory rb30et bottom end, crank rods and pistons, rb25det head, my current hi flowed xtr turbo,850cc powerflow injectors,haltech ecu, rb26dett water pump, stock oil pump, thru a r33 gtst manusl box...iv been told it will be good for 3/320rwkw...duz this sound rite 2 u?

[TTT]

you're using the 30eT bottom end?

If it's a high flowed RB20DET turbo it will run out of airflow at around 260 rwkw

If it's a high flowed RB25DET turbo it will run out of airflow at around 270 rwkw

If it's a high flowed RB25DET Neo turbo it will run out of airflow at around 280 rwkw

That's not your main problem, the RB30ET pistons with an RB25 head will have very, very low compression ratio (in the 7's). That's why we use the RB30E.

cheers

[danielson]

with the rb30e, are the stock rods and slugs strong enough to take the beating? or a $2500 aftermarket jobs the go? think cheap, thats wat im trying to do.... i know i know, cheap usualling ends up being "cheap", but i dnt av THAT ammount of money lying around atm...

I just want to build a torquey motor, turbo upgrade can wait. so 270kw? a the wheels im guessing? why did this guy tell me 320? is he just having a wank? or is he just trying to get work from me?

[Bl4cK32]

any motor can be a tough motor, it depends on how good the tuning is

Im only running 220 rwkw and its a torquey motor. 420Nm (? dunno the scale) and it pulls like a freight train Over 300rwkw and its only a tyre frying machine.

Daniel... As some one prior suggested the RB30ET blocks apparently have piston oil squirters.

You having access to an rb30et block can you confirm this?

[danielson]

The rb30 vl type blocks dont have oil squirters. only the rb20,25,26 have them. a lot of ppl put the rb25det squirters in the rb30 conversions tho...

[GTRgeoff]

This pic illustrates the close curved lines a little better.

Sorry Geoff.. I don't follow the Cap'n...

Do you mean repeated high load that attempts to and may very well slightly bend the teeth every time?

A little like breaking a coat hanger by bending it repeatedly.

So definitely rb30 related?

Sorry mate, I missed the question. Wasn't meaning to be rude.

Basically all steel things have a fatigue load limit. Below that load you can load infinitely (faults notwithstanding) and it won't fail, but increase the load, or in this case torque, and eventually it will start to crack slightly more and more each load cycle until the cross sectional area holding it is too small and just lets go, like the coathanger.

It's a bustard of a job (= costly), and only about 2 in 10 RB30 blocks are suitable. Ceramic coat the piston crowns and oil retention coat the skirts, just as effective.

cheers

[danielson]

how is it only 1 in 10 are suitable? arent the blocks all made the same? or individually cast.....lol but seriously hows that possible?

[platinum]

No RB30 blocks (be it from an RB30ET or RB30E) have oil squirters stock.

[Cubes]

I need to find the bloke who stated the rb30et blocks have oil squirters... Thread was around here some where.
